Edmund's anticipated return to Guiding Light is set for October 24... but what kind of trouble will the former dark prince stir up this time?

Soap Opera Digest got the insight from David Andrew Macdonald, who says he's psyched to be back on daytime for the month-long cameo that's certain to rattle cages all over town.

The actor says transforming himself into Edmund again wasn't hard.

"You do something for six-and-a-half years and you've really worked a lot of it out, so it becomes a bit of muscle memory," he said.

The feeling was mutual for the cast and crew of the show, who welcomed Macdonald back with open arms.

"It's been a lot of fun," Macdonald said. "I got there and the day had moved along really quickly, so they got to my [scenes] just before lunch and I'd spent so much of the morning saying hello to people and talking that, of course, I hadn't really gone back to look at my script [laughs]!"

Viewers can assuredly expect to see Edmund up to his old tricks — and even get a taste of what's been going on in San Cristobel.

"[Edmund's] down there and he runs into some people because they need things that he can do for them," Macdonald said. "But also there are some people who are there independently of that and, of course, he wreaks havoc on them as well."
